Just checked on the CrossStinky app and none of: Durham Tees Valley, Teesside Airport or Middleton St George appear on the list of station names.
No idea what else it could come under.
If you can't book tickets to the station...
Yes it's the 1020 Darlington-Metrocentre and 1050 Metrocentre-Darlington both on Sundays
